The Light that flows through your system is Universal Energy. It is the Light of the Universe. You give Light form. What you feel, what you think, how you behave, what you value and how you live your life reflect the way you are shaping the Light that is flowing through you. They are thought forms, the feeling forms and the outer forms that you have given to Light. They reflect the configuration of your personality, your space-time being.
The formless, what is that? As a pianist, I can best begin to understand through the study of piano music: notes on a page, each one to be taken hold of by the fingers and made to sing. One learns to listen, to seek the composer's intention, to try to recapture the tempo; to give attention to every note, however small, and to love each silence... Music is a transmission from one person to another, a deepening of understanding, and an awakening to the sense of beauty and order which lives deep inside us.
